Specieation of Letters Patent.

To all whom it may concern: l

Be it' known that I, LOUIS D. CAMPS, a citizen of the United States of America, residing in the borough of Brooklyn, cityand Stateof New York," have invented a certain Improved -Attachnient for lVriting- Machines, of which the following .isa specification. y

This invention comprises an attachment for typewritingniachines for performing -what is'knoi'vn, as split`order or split-billing work, and for addressing circular letters, or

vfor still otherpurposes to which'it may be applicable. In socalled split-order worka wholesale establishment may Areceive 'an 'Order for articles'rom various of its departments to each of which a separate order should be sent. All suclrseparate, Or lsuborders, should contain the same information,

data or instructions, such 'as' the manie of the consignee, inode ofshipping, packing, terms of 'payment,` etc. In lnakingup, auchan order, sheets )rinted with suitable caption blanks are placedin the machine with carbon paper intermediate the'c'aptions 'of the sheets and all, such generaldata is printed at one operation, The order for one departmentl of the house is then printed. upon the first sheet below the caption, that sheet is re? moved, and so on until allv the department orders have beenprepared. Devicesfor accomplishinfr this general operation have heretofore been proposed.

The characteristic feature of the resent invention isy that the assemblage o Order sheets is clamped or held at the rear or bottom edges of the sheets.v -The clamp device l must, of Course, be so constructed and arranged that during the operation of printing as the multiple sheets are fed around the platen, it will yield or follow the sheets.'

Vlien theouter sub-order sheet has been printed the clam device is returned to an mitialfposition, t e outermost sheet removed fromtlie platen although it may still be held `by the clamp, and printing upon the second sheet proceeded with. Such isthe mode of I operation of apparatus constructed in accordance with this invention. It has the advantage that the sheets that'are, one by one, removed or displaced from 4the platen-:are

or holding means.

-still held at their rear edges by the clamping Patented Ape 2e, 191e.

In the accompanying drawings: Figure 1 is a plan view: F ig.'2, a side elevation: Fig.

YThe: special construction' of. the' several" `parts of the apparatus illustrated have beenshown'by experiment to efiiciently perform the desired operations but the invention i not limitedv to such details.

The invention is shown as applied to the Royal Typewriter Companys Standard machine. machines ot other style andfother manufacture. The paper feed devices coperatin with the platen are such as have been use( in the Royal Typewriter Companys Standard machine but, of course, any appropriate hind of paper feed devices nia-y be employed.

6 a transverse bar connecting them, an 7` the. paper table extending between the side Plates. l

8 is the rear feed roll, and 9 the front one.

10 is the release-lever for throwing oil' the aper feed. Concentrieally to the axis 11 t e .release lever is formed with gear teeth meshing witha Apinion 1 3 on a rock shaft 14 transversely notched to receive the ends of the. levers that carry the feed rolls and b rotationof which the lever ends are cause to ride upon. the highv parts of the shaftso that the feed rolls are withdrawn 'from the platen.

Mounted upon the side plates of the car- It may, however, be applied to that extends rearwardly and upwardly from the carria e, the side,bars being connected by a cross ar 17 extending between the ends thereof. In .brackets 18 extending rearwardly from the cross bar 17 is mounted the shaft 19, of a spring barrel 20, carrying Agrooved pulleys 21. The spring barrel is i endwise movable bar 25 mounte provided with avusual ratchet 22 and det-ent pawl- 23 having an elongated curved tripping tail 24 that extends to a point adjacent one of the side bars 16 of the frame. 'Cooperating with the end 24 of the awl is an to slide in tixed guide blocks 26, 27, the former of whlch may be applied to the end plateof the typewriter carriage and the latter of which may be ad'ustably se'cured by a set screw 28 on the si e bar 16. A coiled spring surrounding the rod 25 and-interposed between the guide block 27 and an adjustable collar 29 on the rod 25 serves, by its reaction, to urge the rod 25 downwardly. When the is moved upwardly, its forked end 30 acts upon thepawl 24, 23,- and throwsit out of engagement with thegratchet of the spring drum .reaction of which will restore t e -parts to normal position as is. hereinafter described. The sprin drum should be tripped` at the tine the re ease lever is operated to thipw the feedA rolls and the operation of .moving the rod to trip the spring drum pawl 'may be -.conven1ently e'ected by placing on the release lever a cam faced arm 31 by which the rod is urged upwardly when the release lever 10 is drawn forward to throw oli the feed rolls. Ex tending between the side bars 16 and car- I.ried by sleeves 32, 32, that slide 'on these bars is a aper clamp that may be constructed as ,fo lows. Rigid with the sleeves is a transverse late 33 provided with paper gages 34. operating` with this late is a spring pressed clamping bail 35 w lose ends rock .about a transverse 'shaft 36 held in posts437'on the' transverse plate 33. Co'iled Asprings 38 applied to'the rod 36 adjacent its ends have each one en d attached to a collar 39 on the rod and the other end is connected with the bail 35 so that the reaction 'of the springs tends to urge the bail downwardly into contact with plate 33. The bail maybe raisedby''rock shaft 40 turningin bearings in 1|1gs141` on`the under face of plate 33 and 'having railitl' arms 42 to which are pinned4 pitman links 43 extendmor through a ertures 44in pla/te33 and 'pivoted at 45 to t e ends *of tl'ie'bail or clamp bar 35. When theha-'BSis raised by turninvr shaft 40, which is provided with a knurle head 46, it will be held up by a sprin latch 47 at the left hand side ofthe attac ment which then engages the u ppr'edge` or corner Vof the transverse plate 332i Inthis condi` tion, the paper sheets may -conveniently aceomp wound -upon the grooved pulleys 21 andcoil 73 be inserted against the gages on the plate 33 and theA latch 47 tripped.- The sliding clamping frame is to be suitably connected with the shaft 19 of the springbarrel. This may be ished by the tapes48 nect'ed to. plate 33.

The o eration of the apparatus'thus vfar describe is no doubt obvlous 'but 'may be briefly stated. An assemblage of sheets Vclamped at their rear ends is fed aroundthe platen in the ordinary way, the spring barrel yielding and the clamp moving with the sheets. When printing upon a sheet has been completed, the release lever .is o' rated to throw olf the feed rolls and simu taneousl' soY A trip the springdrum, the reaction of whc draws up the clamp and with it the' attached sheets that are now loosely disposed around the platen. With-the devices 1n this condi-r tion, the outermost sheet 'that has'just been 8'5 printed may be withdrawmthe 'otl1 `ers re` maining around the platen,'and}the drawn allowed to hangfrom'th indicated at 49 in Fig.8. 50,l assemblage of sheets remaining` chine.

Movement ofgthe paper clamp aways the platen, when the s ring barrel is trip may be limited by a bar 16. T is stop may be adjusted/ sin'ce both it and the collar 29 are adjustably--- mounted one upon the .framebar 16 andther` other upon the endwise movable' tripping This stop may beset so that when 190 rod 25. the sheets are drawn rearwardly away'from the laten they will be arrested at tlie'4 point at w ich printing is to be commenced on the' next sheet. The clampV 4 acts frictionally upon the sheets to prevent their momentum from disarranging them. Other stopsni'ay be employed, such'for instance, as alateh'=',5 1

ivoted in a recess 52 in the outeraee right hand side bar 16.v Ithas applic toit a sprino' 53 whose reaction tends tot i outwardly as in Figs. 1, 4 ande. ,j

On the endwise movable sprin "v, arrel tripping bar25 is adj ustably mounte ablck 54 that operates t'o press the latch stop ,51 i'nwardly at the proper time. Theopratiqn back andthe triping Yrod returnsto normal' 125 osition, the's ring barrel is rengage yl lts Pawl, .and lock sepfesses the nach 51V inwardly. This stop may serve as theorie to' determinethe initial position of the successive sheets during the 'printing o f the Vorder 139 'awaitef Pe utment kof one:` of the` lsleeves 32 a ainstv th' block 27 on'thfe f raine'b atchpressng it inwardly. 12 0 items, Sleeve 32 may pass between rthe latch. 51 and block 54: when the latter has pressed the latch inwardly. A'stop such as 51 may or. may not b e used since the'sheetsmay be brought to the desired line '.for printing by successive manipulations of the line space, lever of the machine, or 4by direct rotat-ion'\` of the platen. Ifstops such as 51 be employedas I prefer, they maybe made. ad- ]ustable. For that purpose, the block '54 is xed adjustably.- on the tripping rod by means of a set screw and the latch 51 may be made adjustablelengthwise of the side 'Ushaped piece 4Skbetween the sheets ai'eretiacted.
